* CANDY-FUELING JMACHINE.

Application filed October 25, 1923. SerialrNo. 670,669.

To all whom it may concern.

Be it known that I, a citizen of the United States,- residing at Milwaukee, in the county of Milwaukee and State of Vt isconsin, have invented new and useful Improvements in Candy-Pulling Machines, or" which the tollowing is'ayspecification. I

My invention has reference, in its broad aspect, to improvements in that type t of candy pulling machines exemplified by'all floating pulling pins actuated to follow each other in a path contemplated by the figure a 8, and arranged to relatively and alternately intersect and align six timesduring-a single cycle of operation, as defined in my patent #1,278,197, granted September 10th, 1918;

: and more particularly it ismy purpose to incorporate in aisingle, compact and efiicient machine a plurality of all floating pulling *pin units wherebyto-multiply the working capacity of the machine without proportionately increasing the number of parts of the machine, or the consumption of power to operate 1t.

-The concept embodied in my present invention includes, among other equally ad- =vantageous features which will be apparent as the description iprocee'ds; 'first,-- a relatively staggered arrangement of the 'pnlling pins ot the respective units to the endthat the load is balanced, and circulation of air atforded; second, the provlsion of improved drums, each formed with novel, opposed operating. or pin carrying heads whereby the pins of the pulling units arecaused to move simultaneously in paths having similar conformation; third, the employment ofa uni tar y driving element for actuatingthe moving parts of the machine, and; fourth, the provision of a novel, cast and machined, two part housing for supporting and retaining the separate parts of my device.

The particular elements of my candy pulling machineemployed to accomplish the objects attributed to it will behereinafter more fully describeddn detail and specifically pointed out in the claimsv appended hereunto and forming apart ofthis specification.

, In the accompanying drawings wherein is V illustrated the preferred embodiment, "and one slight modification of myinvention Figure l'is a perspective view of the as s'embly, withthe top section of th'ehousing removed to show the arrangement of the in- -z;terio,r elements thereof;

Like characters of reference designate like or similar partsythrou'ghout the several views of the drawings, in-which;-

-The numeral designates the'lower section of my two part, cast housing, the upper section .(2) vof which is normally superposed thereupon and retained in place by bolts (3). The meeting face-of each section is formed with coincidentsemi-cylindrical machined declivities (4) which register to receive theopera'ting mechanism of, my candy pulling machine. Formed drlve gearintegrally with and arranged centrally of each section of the housing and extending longitudinally thereof area plurality of =machine bearing members which are conregister to form the assembly. The identity and functionr ofeach of the [saidbearing members Will'be defined in detail hereinafter. The lower section (1) is formed with legs (6) for supporting the machine upon a suitable base.

Mounted for rotation in the housing are drums (7) having identically formed heads (8) connected by hubs The hubs rotate in bearing blocks formed by registering bearing units (10) of the housing. The heads (8) of each drum (7) consist in circular facing members or plates (11), and

gears (12). The gears (12), of one drum mesh with the gears (12) of the other so that the drums are caused to rotate simultaneously and oppositely. The facing plate and gear on each side of each drum are formed with three notches (13) disposed.

each at a point in the periphery of the facing plate and gear coincident with a third of the circumference.

side of each drum are staggered with re-. spect to each other, and in the assembly the The notches on each notches on'eachside of each drum register with the notches on the corresponding side, of the adjacent drum consecutively as ,the drums are rotated. The portions of the sections of the housing receiving the facing plates (11) and gears (12) are machined to provide loose bearing surfaces (14) and (15) respectively.

In carrying into effect the concept of my resent invention I em 10 six ullin ins (16)three for each side or pulling unit of the machine. The pins (16) are designed to be loosely carried incertain of the notches (13) in the heads (8), with the hubs (17) 7 thereof slidably engaging the annular ribs (18) in the housing and the short or inner end of the pins moving in the track (20) formed between the ribs (18). The pins carried by each side or pulling'unit of the machine are relatively staggered so that a line balance is maintained of the load carried by them, and as there are but three pins for each six notches, and as such notches are relatively staggered with respect 7 lo eachjside of the machine. air circulation is permitted with corresponding increase in working efliciency.

As defined in my Patent #1,278,197 granted September 10th, 1918, the pins con templated by my present invention are all .floating, and are transferable alternately employed to accomplish this result are the same as those described in my above men I end walls" of a slot between adjacent heads (8) to move in a path defined by the figure 8. The shifters tion of the pins on one side of my machine is shown at A, while the corresponding position of the pins on the opposite side is shown at B. As is manifest, when the pins on one side are aligned the pins on the other side are disaligned, or in an intermediate position, due to the staggered relation of the notches l/Vhen the shifter is in the position shown at A the adjacent pin is in process of being transferred from one head to the other through contact of the detent (23) with the hub (17 of the pin, but as the pin is carried down by rotation of the heads its hub (17) strikes the arm (22) of the shifter intercepting its path of travel and throws the shifter to in tercept a pin carried by the same head and transfer it to the other head this position of the shifter and the respective pins. is

mencement of a cycle; the next'stage B- shows the pin 2 asabout to intersect the contemplated line between pins 1 and 3, and the pins again aligned at a different angle. At 0 the pin 3 is about to intersectthe line between pins 1 and 2, and at D the pin 2 is about to intersect the line'between pins 1 and 3. The intermediate positions of the pins are not illustrated "diagrammatically, but are suggested by the view B of Figure 3. In diagrams E and F the pins 1 and 3 are about to intersect the lines between pins 2 and 3 and 1 and 2 respectively, thus completing a cycle of operation. It is manifest therefore, that each. pin intersects an alignment of the otherstwice during a. sin

gle cycle of operation, and that all the pins align themselves six times during the cycle. Candy operated upon by my machineis thus subjected to twelve major pulling actions of the pins during a single cycle of operation of each pulling unit of the machine, as distinguished from a considerably. less number of major pulling actions executed by machines having one or more fixed pins, or those having movable pins carried by rotating arms. I

The actuating mechanism of my candy pulling machine comprises. a transverse shaft (27 hung across an opening in the lower section (1) of the housing, and upon which are keyed gears (28) which mesh with the'gears' 12) of one of the drums. A- drive gear (29) is also keyed to the shaft (27 which is operatively connected with a suitably source of power (not shown). Thus, the respective drums (.7), being flanged portion (32) to travel over a path defined by-the figure *Sin' the manner hereinbefore described. It

will be noted that the machined bearing surfaces (14:) of the housing confine the pins (16) in the proper notches until they reach a neutral point when pins are transferred by the shifter from one drum to the other.

the modified form of my present invention, illustrated in Figures to inclusive, both the housing and operating mechanism are simplified, in that the machined web supported bearing members are dispensed with, and the drums are rotatably mounted and supported directly by the housing (31), which has an annularly extending into the coincident circular openlngs (33) therein which serves both to retain the drums in place and provide a machine bearing surface for'the face plates of the drums. The drums in this form of my invention are provided with relatively short hub portions (3ft) the space thus afforded between adjacent gears (35) serving to confine the hubs of the pulling pins (87) shownin detail in Figure 10. The drive mechanism for this form of my invention consists in a unit comprising two large gears (38) which mesh with gears (35), and an intermediate small'drive gear (39). The unit as a whole is mounted in a vertically extending opening between the housing sections formed by registering recesses (40) therein. Suitable openings (41) are provided in the walls of the recesses for journalling the pins (42) formed on the drive unit. Shifting means (not shown) for transferring the pins (37) from one drum to the other are employed, which same may be of the nature of the shifting means defined in connection with the principal embodiment of my invention.

\Vhile the manner of operating my candy pulling machine is believed to be evident from the foregoing description, it is desired to emphasize the attributes of simplicity and balance attained by the construction defined. The load represented by a batch of candy upon the pins of both pulling units isso distributed that a fine balance is maintained, and sufficient circulation of air permitted to insure maximum efficiency. Furthermore the peculiar construction and arrangement of the housing with respect to the operating parts of the machine provides for a relatively high capacity for work with but slight increase of parts over the candy pulling machine defined by my Patent #1,278,197 granted September 10th, 1918.

*hile in the foregoing, there has been illustrated and described such combination and arrangem nt of elements as constitute the preferred embodiments of my invention, it is nevertheless desired to further emphasize the fact that interpretation of the invention should only be conclusive when made in the light of the subjoined claims.

Having described my invention and its objects with such attention to .detail as will thoroughly acquaint one skilled in the art with its construction and advantages, I

cla-imz- 1.
